Note that some bugs on this list can be remedied, and others not yet. Ideally links would be created in this Wiki leading to the solutions to those issues that can be resolved. If someone can do that it will be useful for the community.

Exchange Activesync (EAS) doesn't work reliably. Every few days synchronization stops, and the only workaround is to reboot phone. In fact, EAS is even less stable than on Aqua Fish / Jolla C. Last stable synchronization was on Jolla 1.

Volume adjustment is not synchronized between Sailfish OS and Aliendalvik (Android apps).

Notifications for Android applications are often in loop.

Camera button does not launch camera application as could be expected (not really a bug, more of a desired feature). (feature added in SFOS 2.1.4.x)

Email application is more like a Powerpoint presentation it is so laggy.

Camera zoom using volume keys does not function (maybe not bug but more of a desirable feature).

Video viewed in browser is not exactly smooth.

When listening to Spotify with bluetooth headset, if wlan is activated the music has small but audible pauses/hicups at regular intervals, probably due to scanning for access points. (workaround, turn wlan off)

Is it possible that bugs, including problems with the 4G? I use a MVNO handler that with Jolla C, I do not mind, while with Xperia it is fixed in 3G.
I tried a sim of a 4G enabled MNO operator and stayed in 4G for a few seconds.

I have an issue where the screen, directly after awakening with a power button press, is totally unresponsive, so you either way for it to time out and re-sleep, or hit the power button twice (to dismiss the awakened screen and then wake it again) in order to be able to swipe the phone on.

I also find the keyboard in Android a little buggy, sometimes touching a text field will bring up the keyboard, but then it automatically disappears after a second.

I also cannot get google maps to utilise the GPS data, I can see with sailfish apps that the GPS is locked in and working, and yet gmaps does not show a location.

I think the worst one is the lack of available system memory. I couldn't even reinstall onto my 32 Gb Xperia all the apps I had on my 16 Gb Jolla.

Additionally, this conclusion of the Oct. 18 meeting appears to be totally unacceptable for those who purchased SailfishX and an Xperia X device to host it:

No safe solutions exist to the two
problems: losing 7 GB to factory
reset, and too small system partition
(rootfs); we'll have in mind to
enlarge rootfs in future devices, for
now just install less apps and use SD
card ;) (sledges, 08:54:50)

I assume the OS development team will not consider this topic closed. I wouldn't recommend buying SailfishX + Xperia X for now, unless a workable solution is made available.

Audio is pretty badly distorted when music plays at low volume, like when a song starts or ends. I suspect some bugs with sampling or power saving, as the Xperia X clearly plays music just fine in Android.

The btrfs file system is not supported anymore (not built into kernel), but the f2fs file system is. However, when formatting a microsd card in Linux, copying music to it and moving the card to the phone, SailfishX only shows the top-level directory. Just creating the file system on Linux and inserting the empty card into the phone works; files on the device are created without a problem over SSH or MTP. I suspect some on-disk format changes, the kernel on Xperia X is pretty old. It might be a good idea for Jolla to include mkfs.f2fs on the device so the GUI can format microsd memory cards and any compatibility issues are avoided.

But few times i used handsfree coorspondent complainded so much about echo it had to be switched off.
In my case handsfree works but sound quality is so poor that it can't be used.
It was in quiet room with phone on a steady wood table at about 50 cm.
Anyway realy like to use sailfish X.

Found an issue in the wifi while traveling to Korea.
I was not able to connect to any 2.4GHz network (actually the search results in the phone seeing only 5G networks).
Using the US regdom (iw reg set US in the terminal) makes the phone to see all wifi networks.

I found the following issues so far. Trying not to double the points others already mentionned.

1) Unsharp pictures, especially in lowlight. hte preview on the Xperia screen looks good, but the photo taken is blury and less sharp than the preview. Big disappointment

2) Shutter sound and shutter action not syncron, esp. with flash

3) white balance with flash way too yellowish

4) wakin the screen takes 0,5s too long. expect a more snappy behaviour. with button as well as with douple tap

5) speaker volume (during calls on loudspeaker) way too low

6) sometimes laggy behaviour, cant say yet in which situations exactly, will have a more close look on this one when it exactly happens. EDIT: Happened during using firefox, scrolling a news webpage

BTW: These points I like about SFOS-X:
- brilliant screen
- hardware that feels worthy and stable
- ability to use SFOS on some piece of fast hardware that doesnt feel outdated
- no overheating/background process overload issues so far
-superb word prediction, Android support
